Мақолада бугунги куннинг долзарб муаммоларидан бири бўлган сув хўжалиги тизимларида сув сарфини ўлчаш масаласи кўриб чиқилган. Тадқиқот объекти сифатида Миришкор магистрал каналидан сув олувчи УР-6 А суғориш канали танланган. УР-6 А суғориш каналининг ПК-1+00-пикетида Миришкор ирригация тизими бошқармаси гидрометр ходимлари билан биргаликда “ГР-21м1” маркали вертушка ҳамда “SonTek” S5 маркали доплер ёрдамида дала тадқиқотлари олиб борилган. Ўлчов ишларида иккита ўлчов воситаларининг аниқлик даражаси, ўлчов жойида фойдаланиш қулайлиги ва иқтисодий самарадорлиги таҳлил қилинган. Ўлчов натижаларига кўра, гидрометрик вертушка орқали аниқланган ўртача сув сарфи Q=2,39 m3 /с, доплер ёрдамида ўлчанган ўртача сув сарфи Q=2,261 m3 /с ни ташкил этди.

В статье рассматриваются вопросы измерения расхода воды в системах водного хозяйства, что на сегодняшний день является одной из самых актуальных проблем. В качестве объекта исследований выбран оросительный канал УР-6 А, забирающий воду из магистрального канала Миришкор. На пикете ПК-1 + 00 оросительного канала УР-6 А проведены полевые исследования совместно с гидрометрами управления ирригационных систем Миришкор с помощью вертушки марки «ГР-21м1», а также доплера «SonTek S5», проанализирована в измерительных работах степень точности двух измерительных приборов, удобность использования на месте измерения, экономическая эффективность. Согласно результатам измерений, средний расход воды, определенный по гидрометрической вертушке, составил Q = 2,39 м3 /с, средний расход воды, измеренный с помощью доплера, составил Q = 2,261 м3 /с.
The article discusses the issues of measurements of water consumption in water management systems, which is regarded as one of the most pressing problems nowadays. The UR-6 A irrigation canal, which brings water from the Mirishkor main canal, was selected as the subject of the study. The field studies carried out at the PK-1 + 00 picket of the UR-6 A irrigation canal, together with hydrometers of the Mirishkor irrigation systems control using a GR-21m1 spinner as well as a SonTek S5 doppler, analyzed the degree of accuracy of the two measuring instruments, the ease of their use at the measurement site as well as economic efficiency. According to the measurements, the average water flow, determined by the hydrometric spinner, was Q = 2.39 m3/s, the average water flow, measured using the Doppler tool, was Q = 2.261 m3/s.
